Description

Technical Field

[0001] The present invention relates to the technical field of bag dust removal, and in particular to a high-temperature resistant bag dust removal filter element assembly. Background Art

[0002] A bag dust collector is an industrial environmental protection equipment that uses filter bags to filter and purify dust-laden gases. It can adapt to a wide range of dust concentrations and can adapt to complex working conditions such as high temperature, high humidity, and corrosiveness by optimizing the filter bag material and cleaning system. It is one of the mainstream equipment for industrial dust control and is widely used in dust-generating industries such as metallurgy, chemical industry, electric power, and waste incineration.

[0003] During high-temperature processing, the filter bags have poor high-temperature adaptability. They tend to shrink at high temperatures and rebound at low temperatures. Continuous friction with the rigid longitudinal reinforcement causes damage, shortening their service life. Second, when the filter bags are damaged, it is difficult for personnel to detect (unless the damage is very serious and almost has no filtering function), and it is difficult to locate them. Traditional detection relies on manual investigation or delayed dust concentration monitoring, which can easily lead to excessive emissions. Third, the pulse injection mechanism is cumbersome to disassemble and assemble. The injection pipe is fixed to the fixed pipe, and the filter bags need to be disassembled one by one when replacing them, which is time-consuming and labor-intensive. These defects lead to high maintenance costs and poor operational stability of the equipment, making it difficult to meet the needs of complex high-temperature working conditions.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 2 as well as Figure 7-11 A high-temperature resistant bag dust filter element assembly includes a dust collector 1, an inspection cover 2 is provided on the dust collector 1, a flower plate 11 is fixedly installed in the dust collector 1, a plurality of plate holes 14 are opened on the flower plate 11, and a filtering mechanism is provided in each plate hole 14. The filtering mechanism separates the dust in the dust-laden airflow so that the final discharged gas meets the environmental protection standard. During the filtering process, the filtering state is adjusted according to the temperature change while locating the damaged part.

[0034] The filtering mechanism includes a filter bag 7 that is snap-fitted into the plate hole 14. The surface layer of the filter bag 7 is made of graphene-modified PTFE fiber. The high-temperature resistance and corrosion resistance of graphene are used to improve the wear resistance and oxidation resistance of the filter material surface. At the same time, the layered structure of graphene can form microchannels to accelerate dust stripping. The middle layer is implanted with basalt fiber, which utilizes its excellent high-temperature resistance and chemical corrosion resistance to enhance the overall strength of the filter material and alleviate the problem of high-temperature shrinkage. The bottom layer is made of nano-ceramic fiber (such as alumina fiber). Through the filling effect of nanoparticles, the porosity of the filter material is reduced and the capture efficiency of ultrafine dust (PM2.5) is improved. A ceramic coating containing nanocapsules is applied to the surface of the filter material. The capsules contain SiO2 aerogel repair agent. When the filter bag 7 is partially damaged (the damaged area is difficult to observe and no obvious airflow changes have occurred), the high temperature triggers the capsule to rupture, and the repair agent fills the crack and solidifies, achieving self-repair.

[0035] A metal spring ring is installed at the opening of the filter bag 7. This metal spring ring is typically made of stainless steel, offering excellent elasticity and corrosion resistance. A suitable space is reserved at the opening of the filter bag 7 for the spring ring. During installation, the spring ring is expanded and placed into the hole 14 of the flower plate 11. The spring's elastic restoring force allows the ring to fit tightly against the edge of the hole 14, thus achieving a sealed connection between the filter bag 7 and the flower plate 11. This also stabilizes the filter bag 7 and prevents it from falling out.

[0036] A flange 8 for sealing and fixing is installed between the filter bag 7 and the flower plate 11. When installing the filter bag 7, the flange 8 can be tightly connected to the flower plate 11 of the dust collector 1 through bolts, nuts and other connectors, so that the filter bag 7 is firmly fixed in the designated position to prevent the filter bag 7 from shaking, shifting or falling off under the impact of the dust-laden airflow, thereby ensuring that the filter bag 7 can perform filtering work stably. A plurality of slide grooves 32 are provided on the flange 8, and the end face of the slide groove 32 is elliptical. A nickel-titanium alloy wire 33 is fixedly installed in each slide groove 32, and a longitudinal rib 28 is fixedly installed at one end of each nickel-titanium alloy wire 33. The upper end of each longitudinal rib 28 is slidably set in the slide groove 32, and a bottom rib 29 is slidably installed on the lower end of each longitudinal rib 28. A nickel-titanium alloy wire 33 is also fixedly installed between the bottom rib 29 and the lower end of each longitudinal rib 28. A plurality of annular ribs 30 are fixedly installed between each longitudinal rib 28, and each annular rib 30 can be stretched and retracted to adapt to the distance changes between the multiple longitudinal ribs 28.

[0037] The filter bag 7 will shrink at high temperatures and relatively rebound at low temperatures. This cycle is prone to fatigue damage (accelerated material aging), and the rigid support of the internal longitudinal ribs 28 cannot adapt to this dynamic change. The nickel-titanium alloy wire 33 can shrink at high temperatures and rebound at low temperatures, bringing multiple longitudinal ribs 28 closer together, changing the support space within the filter bag 7 (reducing the support space), adapting to the temperature changes of the filter bag 7, and preventing the filter bag 7 from shrinking at high temperatures and tightly wrapping around the longitudinal ribs 28, resulting in severe friction between the two (especially under airflow impact), and easily being worn by the annular ribs 30 and longitudinal ribs 28 on the surface of the filter bag 7.

[0038] The upper ends of the multiple longitudinal ribs 28 are fixedly installed with fixed rings, and each fixed ring is hingedly installed with a floating plate 31. When the filter bag 7 is damaged, the airflow in the filter bag 7 changes, driving the floating plate 31 to rotate upward. An alarm is installed in the dust collector 1, and the alarm is connected to the floating plate 31 with an electric wire. The rotation of the floating plate 31 activates the alarm.

[0039] When the filter bag 7 is intact, the dust-laden gas needs to penetrate the filter bag 7 before entering the bag. The filter bag 7 itself has a certain filtering resistance to the airflow, so the airflow speed inside the filter bag 7 is slow and the pressure is relatively stable. At this time, the airflow impact force on the float 31 is small, and due to gravity and the preset balance, the float 31 remains naturally drooping (the force is balanced with the hinge point of the fixed ring). When the filter bag 7 is damaged (such as a hole or tear), the dust-laden gas does not need to penetrate the material of the filter bag 7, and can directly flow into the filter bag 7 from the damaged part quickly, causing the airflow speed at the damaged part to be much higher than the flow speed during normal filtration, forming an upward impact airflow. The gas flowing into the damaged part causes the local pressure to rise instantly (higher than the normal clean air side pressure), generating an upward pressure difference, which pushes the float 31 to be unbalanced. Because the floating plate 31 is a rotatable structure hinged to the fixed ring (without rigid fixing), the high-speed airflow or pressure differential acting on the lower surface of the floating plate 31 generates an upward thrust, overcoming the plate's own gravity (in its initial equilibrium state) and causing the floating plate 31 to rotate upward about the hinge point. The process from the change in airflow to the rotation of the floating plate 31 is almost instantaneous (mechanical action with no electronic signal delay), preventing continued dust leakage from damaged filter bags 7, reducing deterioration time, and lowering subsequent treatment costs.

[0040] Reference Figures 1-6, and also includes a pulse blowing mechanism, which is used to uniformly clean the dust adsorbed on the filter bag 7; the pulse blowing mechanism includes an air storage pipe 3 fixedly installed on the outside of the dust collector 1, and the function of the air storage pipe 3 is to store high-pressure gas. A plurality of pulse valves 4 are fixedly installed on the air storage pipe 3, and each pulse valve 4 is fixedly connected to a fixed pipe, and one end of each fixed pipe is connected to a blowing pipe 10, and a plurality of nozzles are provided on the blowing pipe 10, and each nozzle is located directly above the plate hole 14. A differential pressure transmitter is installed in the dust collector 1. The differential pressure transmitter measures the pressure difference between the two (i.e., "filtration resistance") in real time through two pressure points installed at the inlet pipe of the dust collector 1 (the pipe where the gas to be dusted enters) and the outlet pipe (the pipe where the gas after dust removal is discharged). When the resistance reaches the preset upper limit, the differential pressure transmitter transmits a signal to the PLC control system (installed on the outside of the dust collector 1 to control the dust collector 1, which is a prior art and will not be elaborated on here), triggering pulse cleaning (starting the pulse valve 4 to spray gas, so that the spray pipe 10 sprays gas to remove dust on the surface of the filter bag 7). When the resistance drops to the lower limit after cleaning, the signal is fed back to the PLC to stop cleaning to avoid excessive cleaning that damages the filter bag 7 or wastes the air source.

[0041] The dust collector 1 further comprises two hydraulic rods 5, both of which are fixedly mounted in the dust collector 1. A push plate 6 is fixedly mounted on the driving ends of the two hydraulic rods 5. An auxiliary mounting mechanism is mounted on the push plate 6 for uniformly mounting and dismounting the pulse spray mechanism and adjusting its position to facilitate the installation of the filter mechanism. The auxiliary mounting mechanism comprises a push rod 26 fixedly mounted on one end of the push plate 6. A fixed frame 13 is fixedly mounted in the dust collector 1. A gear rod 12 is slidably mounted on the fixed frame 13. A clamping plate 3 27 is fixedly mounted on the gear rod 12. A circular hole 1 is formed in the clamping plate 3 27. Push rod 26 is slidably mounted in the circular hole 1. A stopper is fixedly mounted on one end of the push rod 26, and the diameter of the stopper is larger than the diameter of the circular hole 1. A gear ring 24 is sealed and rotatably mounted on each fixed pipe. Each gear ring 24 meshes with the gear rod 12. Each gear ring 24 is provided with a thread, and each spray pipe 10 is sealed and connected to the fixed pipe via the corresponding thread. Rotating the gear ring 24 can separate the blowing pipe 10 from the corresponding fixed pipe.

[0042] Two slide rails 17 are fixedly mounted on the flower plate 11. Slide rods 18 are slidably mounted within each of the slide rails 17. Multiple support half-rings 25 are fixedly mounted on one of the slide rods 18. The inner diameter of the support half-rings 25 matches the outer diameter of the blowpipe 10. When the blowpipe 10 is released from the gear ring 24, it will fall onto the corresponding support half-ring 25, which is used to support the blowpipe 10. Multiple limit plates 15 are fixedly mounted on the other slide rod 18. Each of the limit plates 15 has a slide hole 16 formed therein. A square slider is fixedly mounted on one end of each blowpipe 10. The square sliders are slidably mounted within the corresponding slide hole 16. When the blowpipe 10 is separated from the fixed pipe, it will slide within the slide hole 16.

[0043] Both ends of the slide bar 18 on which the limit plate 15 is installed are fixedly provided with springs 19, one end of which is fixedly provided with a card plate 20, and the card plate 20 is slidably provided in the corresponding slide rail 17, and a support plate 9 is fixedly provided on one side of the card plate 20, and the support plate 9 is slidably provided on the inner wall of the dust collector 1, and a plurality of protrusions with a trapezoidal cross section are regularly provided on the support plate 9 (refer to Figure 4 ), a card plate 21 is fixedly installed on one side of the support plate 9, a circular hole 2 is opened on the card plate 21, a circular hole 3 is opened on the card plate 1 20, a push rod 1 22 is fixedly installed on the other end of the push plate 6, a plug 23 is fixedly installed on one end of the push rod 1 22, and the plug 23 is engaged in the circular hole 2 or the circular hole 3 for use. The sum of the length of the push rod 1 22 and the horizontal distance between the card plate 1 20 and the card plate 2 21 (the horizontal distance between the card plate 1 20 and the card plate 2 21 along the length direction of the support plate 9) is less than the length of the push rod 2 26.

[0044] When the filter mechanism needs to be replaced and repaired uniformly, the inspection cover 2 is opened first, and the two hydraulic rods 5 are started to drive the push plate 6 to approach the inside of the dust collector 1. The push rod 22 drives the plug 23 to be stuck in the circular hole 3 in the card plate 20 through the push rod 22. At this time, due to the static friction between the plug 23 and the circular hole 3, the card plate 20 drives the plate 9 to move, and at the same time, the spring 19 close to the push plate 6 is compressed (the other spring 19 is not changed due to the position restriction of the injection pipe 10). As the moving process proceeds , the elastic potential energy generated by the compression of the spring 19 increases accordingly. When the elastic potential energy of the spring 19 is greater than the friction between the plug 23 and the circular hole three, the plug 23 will break away from the card plate 1 20, and the push rod 1 22 drives the plug 23 to move to the circular hole 2 on the card plate 2 21 and engage again; at the same time, the push rod 26 moves synchronously in the circular hole 1 in the card plate 3 27 until the plug 23 is engaged with the card plate 21. At this time, the push plate 6 and the card plate 3 27 are against each other, and the push plate 6 pushes the gear rod 12 to slide in the fixed frame 13, and the spring 19 is compressed again. The movement of the gear rod 12 drives the multiple gear rings 24 to rotate simultaneously. At this time, the multiple blowing pipes 10 are rotated out (the spring 19 is compressed to the maximum state). As the blowing pipe 10 is rotated out, one end of it falls on the corresponding supporting half ring 25, and the other end slides in the sliding hole 16 in the limit plate 15, so that the multiple blowing pipes 10 are completely separated from the fixed pipe. The sliding rod 18 connected to the spring 19 is then released. The compressed spring 19 releases its elastic potential energy at this time and squeezes another spring 19 (the spring 19 away from the position of the hydraulic rod 5) as the push plate 6 moves. At this time, due to the elastic force of the spring 19, the plug 23 moves with the movement of the push plate 6 and separates from the circular hole 2 on the card plate 21), and the sliding rod 18 connected thereto drives the multiple blowing pipes 10 and the multiple plate holes 14 to be dislocated, so that the blowing pipe 10 moves from directly above the plate hole 14 to between two adjacent plate holes 14, and makes the multiple blowing pipes 10 move to the inclined surface position of the trapezoidal protrusion on the plate 9. At this time, the hydraulic rod 5 is controlled to stop working. The position of the blowing pipe 10 facilitates the disassembly, installation and inspection of the filtering mechanism, saving time.

[0045] When the filter mechanism is installed or inspected, the two hydraulic rods 5 are started to shorten their driving ends, and the push rod 1 22 and the push rod 2 26 are driven to move synchronously through the push plate 6. As the push plate 6 moves, the elastic potential energy of the two springs 19 is released. Under the elastic potential energy of the spring 19 and the cooperation of the plug 23 and the card plate 2 21, the card plate 1 20, the support plate 9 and the multiple limit plates 15 are driven to move toward the push plate 6. At this time, the horizontal position of the trapezoidal protrusion on the support plate 9 moves to the multiple nozzles. One end of the tube 10 will push multiple blowing tubes 10 to approach the gear ring 24 during the movement of the abutment plate 9. When the blowing tube 10 is connected to the corresponding gear ring 24, the block on the push rod 26 contacts the card plate 3 27, and the gear rod 12 is driven to move by pulling the card plate 3 27 (at this time, the plug 23 is completely separated from the card plate 1 20 and the card plate 2 21). At this time, multiple gear rings 24 rotate to connect the multiple blowing tubes 10 with the fixed tube again, maintaining the original state of the blowing.

[0046] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
